It would still be more of an NPC class; for reference, a Fighter/Expert gestalt is still pretty weaksauce.
I'd suggest going with the following:
- Samurai/Aristocrat gestalt; it's a nice little boost, and has some nice flavor.
- Give them
Breaking Stare and Interrogator, allow Breaking Stare to apply to Intimidate checks to Demoralize as well as checks made to change behaviour, and allow the 13th level upgrade for Breaking Stare to suppress immunity to fear from any source except type. They are pretty much official anyway; those modifications take it from "oh" to "OH".
- Give them a +1 bonus to all attack rolls made while dual-wielding their katana and wakizashi at 5th level, 9th level, 13th level, and 17th level. Call it "Daisho Mastery" or whatever.
- Give them an extra daily use of Kiai Smite at 3rd level.
And a pair of optional tweaks:
- If you have Oriental Adventures, add Iaijutsu Focus to their class skill list. They have a class feature called Iaijutsu Master, for crying out loud!
- Replace Improved Initiative at 8th level with Quick Strikes.
And one that might be harder to swing, but which would make the Samurai
awesome:
- Replace Iaijutsu Master with Extended Intimidation.
Extended Intimidation (Ex): Whenever a Samurai of at least 5th level makes a successful Intimidate check to change another creature's behaviour, the effects last 24 hours after you leave their presence instead of fading 1d6 x 10 minutes later. In addition, the Samurai may henceforth apply the bonus from Staredown to any Intimidation rolls made against that creature, instead of just Demoralization attempts.
That would move them from "bad" to "I'd consider playing that". They'd have an Intimidate-based social toolkit and a bit more combat power. I'd say they'd then be a pretty decent BSF/Face (hey, that's normally the
Paladin's job!).
I'd add the following feats to round it all out:
Improved Demoralize [Fighter]:You are good at frightening people in a fight.Prerequisites: Cha 13, Intimidate 4 ranks
Benefits: You may make an Intimidate check to Demoralize a creature as a move action.
Special: If you gain the ability to make Intimidate checks to Demoralize creatures as a move action from another source, you may instead make those checks as a Swift action.
Quick Strikes [Fighter]You can lash out quickly with your off-handed weapon, helping you work it into your combat routine.Prerequisites: Two-Weapon Fighting, BAB +6
Benefits: Whenever you make at least one melee attack with a weapon and are wielding a weapon in your off-hand, you may make an off-hand attack at your full BAB; this does not stack with any other off-hand attacks you might have, such as the one you get by full-attacking while two-weapon fighting. In any round that you use the off-hand attack granted by this feat, take a -2 penalty to all attack rolls.
Terrifying Gaze [General]:Your stare makes people's hearts skip a bit.Prerequisites: Breaking Stare, Staredown, Intimidate 8 ranks
Benefits: Whenever you successfully Demoralize a creature, they are also rendered Flat-footed for one round.
